EGG-CANDLING DEVICE.

Specification of Letters Patent.

Patented July 11, 1916.

Application filed July 12, 1915. Serial No.39,433.

To all whom it may concern:

Be it known that I, LUDWIG IRVIN HniL- BRUN, a citizen of the United States, residing at Sagamore, in the county of Armstrong and State of Pennsylvania, have invented certain new and useful Improvements in Egg-Candling Devices, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved egg candling device and has for its primary ob- ]ect to provide a very simple and serviceable egg testing or candling device whereby the testing of eggs in large quantities is greatly expedited and facilitated without sacrificing accuracy in the operation. 1

It is an additional object of my invention to provide an egg candling device employing an incandescent electric light bulb for the production of an artificial light through the medium of which the condition of the eggs is ascertained, and means whereby the glare of the light is softened and its deleterious effects upon the eyes of the operator entirely obviated.

In a more specific aspect, my invention has for its principal object to provide an egg tester which embodies in its construction a casing having a removable, inclined top provided with a pair of padded egg receiving openings, a reflecting mirror arranged in the base of the casing and provided with a vertically disposed circumscribing flange, and an incandescent electric light bulb adapted to be adj ustably mounted on said flange over the mirror.

It is a further general object of the invention to improve and simplify the construction of egg testing devices of the above character and to provide such a device which can be produced at smallmanufacturing cost and is highly reliable and serviceable in practical operation.

l/Vith the above and other objects in View, my invention consists in the novel features of construction, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawings, in which,

Figure l is a perspective view showing my improved egg candling device mounted in position for use; Fig. 2 is a vertical section through the device; Fig. 8 is a section taken on the line 83 of Fig. 2; and Fig. 1 is a detail perspective view of the adjustable incandescent electric. light bulb.

Referring in detail to the drawing, 5 desig nates the body or casing of my improved egg candler. This casing is preferably constructed of tin or other sheet metal and the opposite side walls thereof are equipped with suitable electric light bulb sockets, indicated at 6. One of thesesockets is adapted to receive a bulb of 110 volts capacity, such as iscommonly employed in house wiring, and the machine is equipped with the necessary wire for this bulb, connected to the socket 6 and a plug indicated at 7 for engagement in one of the lamp sockets. The other of the sockets 6 in the wall of the casing 5 is adapted to receive a bulb of smaller capacity which is operated from electric batteries. In the base or bottom of the casing 5, the concave mirror,,shown at 8, is suitably mounted and secured, and there is a circumscribing upstanding flange or collar 9 surrounding this mirror and secured to the,

bottom of the case.

It is generally admitted that the artificial electric light is preferable in the candling of eggs. Such light is always obtainable and is, therefore, more convenient for the purpose than natural daylight reflected from the face of a mirror. -I, therefore, employ an incandescent electric light bulb 10 of small capacity, which is removably engaged in a suitable socket'll. To this socket, a bracket or clip member 12 is attached, said clip member having three arms or prongs,

as clearly shown in Fig. 4: of the drawing. In mounting the electric light bulb in position, two of the bracket arms are adapted to be engaged upon the, inner face of the upstanding flange 9. while the other arm engages over the outer face of this flange. By the provision of this holding or supporting bracket, the electric light bulb may be readily adjusted and its position changed upon the vertical flange 9. The lead wires 18 for the electric light bulb extend out through the back of the casing 5 and are connected to the opposite sides of a battery, indicated at 14. It. will be observed that the electric light bulb socket is obliquely inclined downwardly with respect to the vertical flange 9 upon which it is mounted, so that the bulb will be disposed contiguous to the face of the concave mirror 8.

The top of the casing 5 is obliquely inclined and provided with an opening.

15 designates a movable top or cover having a flange 16 to fit within the opening in an apertured ear or lug 21 fixed to the and the hips of the operator.

rear wall of the casing 5 adjacent to its lower end. A clamping screw or bolt 22 is disposed through openings in the spaced arms of the rod 20 which coincide with the opening in the ear 21, said clamping screw being threaded in one of the ears on the rod. By adjusting this screw, the casing 5 of the egg tester may be securely held in various angular positions with respect to the rod. Upon the rod 20, the longitudinally adjustable bracket members 23 are arranged and adapted to be securely held in spaced relation to each other on the rod by means of suitable set screws 24. These bracket members may be engaged with the backof an egg crate, bars or cleats secured upon a wall, or to any other convenient stationary obect.

In use, the device will preferably be so mounted that the casing 5 will be disposed approximately midway between the eyes This casing can, however, be readily adjusted to suit the convenience of the individual user.

In the use of the device, the socket 11 carrying the bulb 10 is adjustedupon the vertical flange 9 so that the concave mirror 8 will reflect the light rays upwardly in the proper direction through the eggs arranged in the openings 17 of the cover 15. By

adjustably mounting the socket 11, the electric light bulb may be positioned over the mirror so that the direct glare from the light will not pass through the openings 17 and possibly injure the eyes of the oper- 'ator. The light rays are directed upwardly by the flange 9 and the electric light bulb mounted upon this flange can be very easily and quickly adjusted to the desired position by lifting the top or cover 15. This removable cover also permits the interior of the casing to be readily cleaned in case any of the eggs should be broken in placing the same in position within the opening 17 It is manifest that the device maybe constructed in various sizes and that the supplementary bulb sockets for use when the lamp is wired to the house current, may be eliminated if desired and only the battery operated lamp employed or vice versa. The device is also susceptible of considerable modification in the form, proportion and arrangement of the several parts and I, therefore, reserve the privilege of adopting all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is 1. An egg tester including a casing having an egg receiving opening in the top thereof, a reflecting medium within the easing and positioned below the opening, an upstanding flange surrounding the reflecting medium, a lamp, and means carried by the lamp whereby the same may be detachably engaged with the upstanding flange.

2. An egg tester comprising a casing having an egg receiving opening in its top and adepression in its bottom, a concaved reflector fitted within the depression in the bottom, an upstanding annular flange can ried by the bottom of the casing and surrounding the reflector, and an illuminating member provided with means whereby it may be detachably engaged with the upstanding flange.

8. An egg tester comprising a casing having an egg receiving opening in its top and a depression in its bottom, a concaved reflector fitted within the depression in the bottom, ar. upstanding annular flange carried by the bottom of the casing and surrounding the reflector, an illuminating member provided with means whereby it may be detachably engaged with the upstanding flange, and means carried by a side wall of the casing for detachably supporting the illuminating member.

In testimony whereof I hereunto affiX my signature in the presence of two Witnesses.
